FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent N0. 786,779, dated April4:, 1905.

` Application filed April 4, 1904. Serial No. 201,406.

To @ZZ whom t may concern:

Be it known that I, WILLIAM W. SYKEs, of Minneapolis, Hennepin county,Minnesota, have invented certain new and useful Improvements inFire-Extinguishers, of which the following is a s ecification.

My invention re ates to fire-extinguishers, and particularly those ofthe hand type.

The object of my invention is to provide a fire-extinguisher of simpleeconomical conmunicating with said receptacle and with the space betweensaid plugs.

In the accompanying drawings, forming part of this specification, Figure1 is a vertical section of a lire-extinguisher embodying my invention.lFig. 2 is a section on the line a: of Fig. l. Fig. 3 is an enlargeddetail view of the top of the receptacle.

In the drawings, 2 represents a bottle# shaped glass receptacle having aneck 8, provided at a point referably about midway between the shoul erof the bottle and the outer end of the neck with an annular groove 4,which weakens the neck sufiiciently to cause breakage. at that pointwhen the outer end is struck a quick sharp blow. A plug or'stopper 5 isfitted within the neck lbelow the groove 4 and is prevented from beingaccidentally forced out of place by an annular rib 6. A second plug orcork 7 is provided in the neck above the groove 4 and is preferablysecured by the usual wiring means 8. A space is formed between thecontiguous ends of the plugs or corks, and a tube 9 leads from saidspace through the inner cork to a point near the bottom of the bottle.

The bottle is filled in the usual way with water charged withcarbonio-acid gas at any suitable pressure. In case of fire the personusing the extinguisher grasps it with one hand, knocks off the upperportion of the neck across the edge of a chair, table, or otherconvenient object,.holding the bottle, as a Roman candle is usually heldin the hand, and directs the stream of charged liquid upon the fire. Alarge percentage,v of the gas will ,follow the liquid and aid materiallyin extinguishing the flames.

The liquid in the bottle can be placed under any desired pressure,according to the strength of the receptacle, and the device will alwaysbe ready for use, it being only necessary to knock off the top of theneck to release the entire charge of the bottle.

I claim as my invention 1. As a new article of manufacture, a receptaclehaving a neck provided with a weakened area, means closing said neckupon each side of said area, and a tube communicating with saidreceptacle and with the space between said closing means.

2. As a new article of manufacture, a bottle having a neck provided withan annular groove therein, plugs provided in said neck above and belowsaid groove, and a tube communicating with the interior of said bottleand with the space between said plugs, for

Y the purpose specified,

3. As a new article of manufacture, a bottle adapted; to contain aliquid under pressure and provided with a neck having a weakened area, arib below said area, plugs closing said neck above and below said areaand rib, and atube communicating with the interilor of said bottle andthe space between said u s. p 4g As a new article of manufacture, abottle adapted to contain a charged liquid and having a neck providedwith a weakened area, closing means for said neck above and below saidarea,and a tube communicating with the interior of said bottle andextending partially through said closing means.

5. As a new article of manufacture, a bottle adapted to contain liquidunder pressure and having a neck provided with a weakened area, astopper closing said neck below said area, and a tube communicating withthe interior of said bottle and extending through said stopper'. 1c Inwitness whereof I have hereunto set my hand this 31st day of March,1904:.

WILLIAM IV. SYKES. In presence of- M. HAGERTY, C. G. HANsoN.
